 n. 419). Plantam masculam, ab Hampk 1. c. descriptam, in 

 Australia orientali subtropica legit Eaves. 



Folia caulina plantse masculse haud integerrima, ut 1. 

 c. dicit Hampe, sed apice serrulata sunt.

 scenti-lutescens, nitidiusculus ; caulis gracilis, arcuatus, adscen- 

 dens, divisus, ramis adscendentibus, sat dense pinnatim ra- 

 mulosis, ramulis brevibus, vix ultra 7 mm. longis, arcuatis,

Patria. Nova Hollandia, Manning River, ubi anno 

 1882 plantam masculam legit Gross (n. 169). 



Ab A extenuato (Brid.) Mitt. exiguitate omnium parti- 

 um cellulisque sublgevissimis differt. 



This species comes near to A. extenuatum, but is 

 much smaller than the numerous specimens of the latter, 

 which I have received from Victoria, Tasmania and New 

 Zealand, besides v^hich its cells are almost smooth. D:r G. 

 MuELLER considers it to be a very distinct species, w^hich 

 comes nearest to Hypnum polyurum G.-Miill. in herb.

Dioicum; caespitosum, csespitibus laxis, superne viridi- 

 bus, rigidissimis ; caulis 4 — 7 cm. altus, procumbens, e basi 

 usque fohosus, superne fastigiatim divisus ; folia rigidissima, 

 sicca adpressa, humida erecto-patentia, haud subsecunda.
